Abstract

A method of analysing the structure of bone tissue comprises placing first and second electrodes in electrical contact with the bone tissue to be analysed such that the bone tissue forms at least part of an electrical circuit between the first and second electrodes. Alternating electrical signals are applied to the circuit and the electrical response of the circuit is monitored. The monitored response is processed to generate output data representative of the structure of the bone tissue.
